T BISSELL CARPET SWEEPER COMPANY, OF GRAND RAPIDS, MICHIGAN CARPET SWEEPER Application filed August 31, 1925. Serial No. 53,653.

This invention relates to improvements in carpet sweepers. It relates particularly to improvements in the dust pan structure.

The object of the invention is to provide a ositive pan'stop to keep pans from opening eyond center, to simplify the spring structure of the dust pan,-and at the same time provide a stronger end by eliminating the slots in the ends of the casing which are now 1 necessary in the present construction in order to provide a space in which the spring may operate.

Objects pertaining to details and economies of construction and operation of my invention will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of dust pan features for carpet sweepers is clearly illustrated in the accompanying drawing forming a part of this application,

in which:

Fig. I is a perspective view of the casing of a carpet sweeper with my improved dust pan in place, the floor wheels and brush, and driving mechanism being omitted.

Fig. II is a transverse enlarged detail sectional View taken on the plane of line 22 of Fig. I showing the dust pans-.in operative position. a

Fig. III is a-similar sectional view showing the action of my device with the dust pans dumped.

Fig. IV is an'enlarged detail sectional view on line 4-4 of Fig. II showing the engagement of the operating lever with the central upward bend of the spring.

Fig. is an enlarged detail view with parts broken away showing the details of connection of the lower end of the spring with the dust pan, the same being taken on a line corresponding to line 5-5 of F ig. VI

Fig. VI is a detail sectional view on line 66 of Fig. V showing details'ofthe pivotal support for the dust pan, the sprin connec tion and the manner of retaining t e parts in engagement.

Fig. VII is an enlarged detail sectional view on line 77 of Fig. V of the corner of the dust pan showing the stop for the pan when open.

In the drawing the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference indicate similar parts in all of the views.

The parts of the drawing Will be identified by their numerals of reference.- 1 is the casmg of a carpet sweeper. Z is the end of the casing suitably slotted and perforated to receive the various parts of a carpet sweeper. 3, 3 are the dust pans of the usual form carried on pivots 4, 4 at'the usual point of pivoting. 5 the dust pan, also of usual construction. 6 is the spring for actuating the dust pans and holding them in closed position. It is bent upwardly at 7 at the center and extends lat erally at 8 into pivotal connection with the dust pans 3 which are perforated at' 31 for that purpose. At the point of perforation the sheet metal of the dust pan is depressed or indented at 32 to form the limiting stop 33 for the'said dust pan when dumped, and also accommodates the thickness of the spring. By forming this depression in 'the metal it is possible to avoid slotting and cutting in the end of the casing, thereby enabling lighter material to be used in the end of the casing, and also securing greater free dom of movement of the spring.

The dust pan at the point of indentation is reinforced by the extension 33, the end thereof folded over on the side, so that the structure is entirely formed as a stamping without the necessity of any soldering operation. and can therefore be produced with a minimum of labor and without any special labor operation for the purpose of connecting the sprlng.

The spring is operated by the usual lever 9 pivoted at 10 at the end of the casing having a lateral extension 91 which extends under the center loop 70f t-he spring as seen in Fig. IV. The outer end of the lever terminates in a suitable finger piece .92, of the usual construction.

My improvement especially consists in avoiding the labor operations necessary in slotting the casing for thereception of the spring and providing for the effective location of the spring in thestamping operation in forming the dust pan and provides an improved limiting stop for the dump position.

Having'thus described my invention, what I claim as new and desire toisecure by Let ters Patent, is: I

1. In acarpet sweeper, a casing, dust pans formed of sheet material pivoted within the casing with indented stop depressions to receive the spring connection, and forming stops to cooperate with the spring and limit the opening of the pans, a bent spring with central upwardly projecting loop and with a end to engage the said dust pans and disposed in and cooperating with the said stop depressions and extending upwardly within the casing free to move on the inner surface of the end thereof for controlling and limiting the movement of the said spring and pans, and an actuating lever with finger extending under the spring loop to elevate the same and control the dust pans, all coactingsubstantially as described for the purpose specified. l

2. In a carpet sweeper, a casing, a dust pan formed of sheet material pivoted within the casing with an indented stop depression to receive the spring connection and form a stop to cooperate with the spring and limit the opening'of the pan, a bent spring with central upwardly-projecting loop and with a lateral extension to engage the said dust pan, and disposed in and cooperating with .said

stop depression and extending upwardly within the casing, ,freeto move on the inner the end of the casing for controlling and limiting the movement of i and pan', and hand lever actuating means for said spring.

3.. In a carpet sweeper, a casing, a dust pan formed of'sheet material pivoted within the casing with an indented depression to receive the spring connection, a bent spring with central upwardly-projecting loop and with a lateral extension to en age thesaid dust pan, anddisposed in and cooperating with said depression and extending upwardly within the casing free to move on the inner surface ofthe end'of the casing for controlling the movement of said sprmg'and pan said spring itness whereof I have hereunto set my IRA J.
